Inpex acquires stakes in GOM Lucius project

Anadarko sold 7.2% Lucius stakes to welcome Inpex

Anadarko Petroleum Corp. (Anadarko), formaly Kerr-Mc Gee, and its partners, Apache, Eni, ExxonMobil, Petrobras and Plains Exploration & Production (PXP), had sanctioned the development of the Lucius project in December 2011.

In July 2012, Anadarko sold 7.2% of its interests in Lucius to Teikoku Oil, a wholly owned Inpex company in USA, for $556 million.

As a result, the working interests in Lucius oil and gas field are shared between:

 – Anadarko 27.8%, the operator.

 – Plains Exploration & Production PEP 23.33%

 – Apache 11.7%

 – ExxonMobil 15%

 – Petrobras 9.6%

 – Inpex troughTeikoku Oil 7.2%

 – Eni 5.4%

With the Lucius project, Anadarko and its patners are developing the Blocks 874, 875, 918 and 919 (Lease OCS-G-21444) in the southern part of Keathley Canyon in the deepwater of the Gulf of Mexico.

Lucius is an oil and gas field located 350 kilometers offshore Louisiana in 2,172 meters water depth and a total depth of 6100 meters.

Anadarko and its partners estimate the recoverable reserves in Lucius to 300 million of barrel oil equivalent (boe).

In addition to the Blocks 874, 875, 918 and 919 developed by Anadarko and its partners, the Lucius project should also handle the natural gas produced from the near by Hadrian South field belonging to other stakeholders.

As the operator, Anadarko awarded all the key packages of the Lucius offshore platform to the engineering companies in order to start operation at the end of 2015. 

Technip won SPAR, Subsea and PMC packages 

Because of the mix of oil, gas and condensate to be extracted from Lucius, Anadarko selected the concept of Single Point Anchor Reservoir (SPAR) as this design allows to treat and store liquids before export.

As the master piece of the project, Andarko send a letter of intent (LOI) to Technip in August 2011 to begin engineering, procurement, construction (EPC) and transport of the SPAR hull.

This SPAR hull is designed by Technip Houston Office, Texas, to weight 23,000 tonnes and will be executed in Technip’s shipyard of Pori, Finland.

The Lucius SPAR will have the capacity to treat:

 – 80,000 b/d of crude oil

 – 450 million cf/d of natural gas

In addition to the SPAR hull, Anadarko awarded Technip the overall Project Management Consultancy (PMC) contract and the Subsea package on a lump sum turn key (LSTK) basis including the:

 – Installation of a flexible flowline, multiple flexible gas lift jumpers, main gas lift and infield umbilicals, subsea distribution units, electrical, fiber optic and hydraulic flying leads.

 – Design and fabrication of the flexible flowline end termination

 – Fabrication and installation of rigid jumpers

 – Burial of flowlines

 – Flooding and hydro-testing of the flowline system.

Technip will perform his Project Management Consultancy (PMC) role from its Houston Office, Texas, USA, and will use its recent acquisition of Global Industries for the implementation of the subsea work.

Mustang won Topsides EPC contract for Lucius 

In December 2011, Mustang Engineering (Mustang), from the Wood Group, completed the conceptual study and the front end engineering and design (FEED) of the Lucius project for Anadarko.

Then Anadarko and Mustang signed the contract for the engineering, procurement, construction (EPC) for the Topsides to be supported on the Lucius SPAR floating production unit.

Mustang and Anadardko have a long standing experience and collaboration in designing and constructing Topsides  equipment for Technip SPAR structures, since the previous Boomvang, Nansen, Gunnison and Constitution projects.

Anadarko and its partners Apache, Eni, ExxonMobil, Petrobras, Plains Exploration & Production (PXP) and Inpex have designed Lucius project as to provide a large infrastructure for further developments of the exploration and production in this area of the Gulf of Mexico where additional prospects and opportunities have already been identified with an active drilling program beginning around Lucius in 2012.
